How to instantiate Resource Prefabs with they names from List?

Hi,

I have found objects and added names of them to the first list and the positions in the second and the rotation in third list.

Code (CSharp):

1. publicList<Game> prefabNameList = newList<Game>();
2. publicList<Game> prefabNameTransform = newList<Game>();
3. publicList<Game> prefabNameRotate = newList<Game>();

I'd like to instantiate the objects from the list, back to saved position and rotation.

WORKING CODE, I see all data in lists in the inspector

Code (CSharp):

1. GameObject[]go = GameObject.FindGameObjectsWithTag("Player");
2.                         foreach(GameObject AllgameObjectsSave in go)
3.                             {
4.            
5.                         Vector3 AllObjectsPOS = AllgameObjectsSave.transform.position;
6.                         Vector3 AllObjectsROT = AllgameObjectsSave.transform.eulerAngles;
7.                
8.  
9.                         prefabNameList.Add (new Game(AllgameObjectsSave.name));
10.                         prefabNameTransform.Add (new Game(AllObjectsPOS.ToString("G4")));
11.                         prefabNameRotate.Add (new Game(AllObjectsROT.ToString("G3")));

WRONG CODE:

Code (CSharp):

1. for (int i = 0; i < prefabNameList.Length; i++)
2. {
3.     GameObject go = Instantiate(prefabNameList[i], prefabNameTransform, prefabNameRotate) as GameObject;
4. }

 

How does the behavior you see differ from what you expect? Do you see any errors in the console? (I already know you do, I can see at least two. But if you get an error message, you should always include it with your forum post)

 

You have right, but my instantiate code is a big mistake, just I putted in as an idea.

 

OK. So, let's start with the obvious: You're using List for those, and List doesn't have .Length - List uses .Count instead.

Second: what is "Game"? it looks to me like it's just a way to store a string. At best it's a poorly named class, but I suspect it's a completely unnecessary one, and you should probably just use strings directly. In any case, you need to create and use a way to extract Vector3's and Quaternions from your "Game" class or string. You'll probably need to parse them.

Also, you're sending your Instantiate function the entire List of positions and rotations; you need after them.

All of those are things to fix -before- we answer the question you actually asked. And it is pretty straightforward:

Code (csharp):

1. GameObject myPrefab = Resources.Load<GameObject>(prefabName);
2. GameObject spawnedObject = Instantiate<GameObject>(myPrefab, pos, rot);

 

Sorry for late answer, but I have tried to understand your describe.


I rewrote the codes, please check again:
I can save and reload the first found object with position and rotation.
This method is save only one name of object, position and rotation.
How can I save all objects, them positions and rotations?
You can try my project:
http://terberendezo.alexbutor.hu
user: a
pass: a
First drag elsewhere all object with mouse, than:
Click on 6th icon.
Save the state (Az összeállítás mentése)
Then load the state (Korábbi betöltése)
(Only prefab save, not binary or network, therefore every time you open the project in browser, then saved will be deleted.)
I hope you could help me, thanks.
